I am 52 yrs old and had a unicompartmental knee replacement 5 years ago. It was very successful and I have had no problems until a few months ago when my knee started to give way, and I would then have excruciating pain in my knee and not be able to weight bear until I had bent and straightened my knee several times. Eventually something would clunk back into place and it would feel OK ish again. Recently I have also had swelling and crepitus (creaking) and walking is limited without pain, not helped by OA in the other knee. My orthopaedic surgeon has told me it is likely that as there is now some deterioration to the lateral compartment this causes strain on the joint and the bearing is moving as the joint opens up. He has recommended a total knee replacement. Has anyone had revision surgery to TKR and if so how did it go? Is it a longer recovery time?
